I am now wondering about the distributor cap, wires and spark plug that I used.

The wires and distributor cap are duralast. Reading the product details on the Bosch wire set and the duralast wireset the only dif I see is that one set (bosch) use's a resistor in the boot. The duralast says nothing of the nature. I am also thinking that they sold me resistor type plugs.

Could this have any impact on the car?
